Informed consent requires which elements to be present?

• A. A signature from the patient only
• B. Disclosure of treatment details and risks, voluntary agreement, and understanding of alternatives
• C. Financial consent only
• D. A nurse's assessment of readiness

Answer: (B)

Informed consent is a process that centers on the patient’s autonomy: they receive enough information to decide, understand what is being proposed, and freely agree or refuse. The best answer reflects three essential elements: disclosure of the treatment details and associated risks, voluntary agreement by the patient, and understanding of available alternatives. For consent to be valid, the patient must have the capacity to decide, information must be given in understandable terms with an opportunity to ask questions, and the patient must know they can choose among alternatives or decline treatment. A signature alone does not demonstrate understanding or voluntariness, so it isn’t sufficient by itself. Financial information or a nurse’s assessment of readiness do not replace the patient’s informed decision about clinical options.
